rear pinion seal leaks - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 3/4 ton 4X4 with a perfectly round 10 bolt rear that the gearset comes out the front of the axle (eaton?). Is a 4:10 posi unit. Any suggestions on keeping the pinion seal from leaking? Seal was recently replaced but didn't fix the leak. Maybe in wrong? or can they be put in wrong? I have seen posts that these rears leak badly, has anybody got a fix besides changing the rear. Doesn't leak anywhere else. The engine a different story though, I keep the dust down on the road wherever I go. lol
